From Trend Micro Labs Blog:
Today I was scanning through various industry blogs when I stumbled upon an entry from a certain competitor. What was interesting was that under the veil of improving Testing quality, the blog openly admitted that the organization in question had been trying to play tricks on competing organizations just to position itself favorably in the media.
They explained that they had deliberately created clean files and added fake detection in order to "show" that other vendors copied them. This was a risky decision. Across the industry, research organizations share a level of trust and participate in sample sharing programs in order to enable the protection of customers – which for Trend Micro, is what always comes first.
Aside from their prank, we were very pleased that the other resounding message that came from the blog post was that they finally understood and supported the message Trend Micro has been promoting for a long time – the need for a change in testing methodology to include real-world testing, such as is delivered by NSS Labs.
